Wow what a trip! Sort of excited that I finally got my app to work in a production environment.

Having to learn Docker like real fast, and then really having to understand how .Net Core 2.2 works. What made it worst was wrapping Angular V7 in .Net Core 2.2, making it much more complicated now. And then connecting it to MongoDB running in another container.

Working with VS2017 and Docker
VS2017 gives you the ability to run your .Net Core 2.2 app in a Docker for Windows container so you can test and debug. But after creating the container, you can't start it again unless you use VS2017 to run it again. What ends up happening is that VS2017 does 1/2 the work in the background and uses the needed components from your shared drive and you can't see it unless you look really close at the output. Now try and use release to build that app and put it in a container, still won't work because your missing the rest of the files needed to run it that are on your shared drive. When you go to peek inside a debug container, it's totally different than a release container. You have to alter your Dockerfile to copy the rest of the files needed to run isolated without a shared drive. Then when you push to Docker Hub you will have everything required.

Visual Studio 2017 will program your environment variables, but to run self contained you have to create them in your Dockerfile or docker-compose.yaml file. eg. DOTNET_RUNNING_IN_CONTAINER=true

VS2017 and Azure:
I actually got to the point where I thought that Docker support for VS2017 was locked into Azure, and that they didn't want us to host Docker containers ourselves, but that was not the case. What it boiled down to was going back to basics and building my project by command line to better understand how "dotnet" works and then build the Docker container. Once I understood the relationship between the two, I was able to go back to VS2017 and craft a better Dockerfile, and then compose it. But what works in Docker for Windows is a whole different story in Docker for Linux.

So to answer some questions that you may have:
Can you host your .Net Core 2.2 app in Docker just using Kestrel - YES
Can you program Kestrel to use SSL with an embedded PFX file - YES

Can you control Kestrel's ciphers such as TLS, no SSL - YES
Do you need a reverse proxy server such as Nginx - NO - so far I haven't had to
Will the stock Dockerfile work - NO - You have to modify it to your needs
Do the current MongoDB C# V2.8 drivers work with Docker and .Net Core 2.2 - YES - but programing the connection string is different than not being in a container. SHA256 auth errors.

Some Advice:
Learn "dotnet" command line first before learning Docker.
Carefully prepare your Programs.cs file for Docker, because if this file crashes your container startup, you won't be able to debug it. No logs, nothing. Add Logging to your Programs.cs will help isolate issues.
Don't hard code much, use json files instead.

Don't trust search engine results:
The most frustrating part is the ocean of outdated information on the internet. When I started learning Angular, all the information was outdated and for V2 and not V6. But it's been cleaned up now. It's the same for .Net Core 2.2 and Docker in which the info is outdated.

Port Numbers:
The other frustrating issue is port numbers. Why does .Net Core want to use ports like 5000, 5001?
When you develop for IIS, normally the port number is 44367 or something. I still don't have the answer for this but used ports 80,443 any ipAddress in Programs.cs and set the ip address in Docker. This took the longest to understand.

Version of Linux:
I tried 2 versions, CentOs and Ubuntu. Not being a fan of Ubuntu, I used it because of it's small footprint and builtin Docker, Docker-Compose support. The build size is so small, I think I can run this on a Raspberry. So Ubuntu Bionic Beaver V18 worked the best.

So what's next?
I'll cleanup my website content at home and run the Docker Compose production version for a couple of weeks. Then build the next server with Docker Swarm and see how that works.

But I need to get more knowledgeable about it first. A couple of things back fired on me as I tried to perfect Kestrel to obtain a "A" rating on GMetrix, but I figured it out. As I perfected external HTTP request, I broke the internal HTTP request.

And I still have to fix the problem with using the refresh button on the browser which is an Angular or SPA issue not playing nice with .Net Core's routing. I see Microsoft has created a new project template for React/Angular/SPA that seems to have fixed it; and it uses a more native version of Angular for wrapping without using Web Pack. This I'm happy to see because it makes more sense to be able to just create an Angular project and then wrap it in .Net Core.

But overall, just getting .Net Core 2.2.4 working in Docker for production use using SSL would be a good place to start.
Maybe later this month. The link below is a working example of the project running in Docker using just Kestrel. It's a work in progress, the refresh button may not work, and I'm trying to determine the best way to fix it.

Actually in my GirdView link button click open new page with passing more than one values usin querystring. Now we want to remove querystring. And we don't want to use session. is their any process to pass values.
Thanks

Your question is not much clear but your query will return you data for whatever date you pass as parameter and if Tblemployee has the data. if you just want to get expiry data for next 30 days you should have logic not to pass future date.

You should return a model when you read the database.
A model is a strong typed class that you use to store data in.
Once you have the model populated, you can add 30 days to the date column by using .AddDays(30) in a loop.
So matter what month it is, it will calculate the proper date.

Hi Friends,
Can anyone help me with this?
Using 3 tier architecture,how to fetch data directly from database table to textboxes when I clicked on select button in grid view,I have a table in SQL database.Upon clicking on select link button in grid view,the selected row values must be fetched from database table to text boxes and must be filled with respective values according to database table.I have used sqldatareader, taken OnSelectedIndexChanged ,written query in stored procedure for fetching selected row but values are not binding to text boxes.Any suggestions would be helpful.

1. You have populated the result into arraylist object which is local to this function
2. You executing command object with ExecuteNonQuery, Reader and DataAdapter
3. You populated Dataset to return from FetchDetails in DAL and did not received it in calling method to bind data.

Populate your local variables in SelectChange event from DataSet object you reveiced from BAL and should work for you.
